Application filed February 6, 1926. Serial No. 86,548.

My invention relates to improvements in skis, and consists in thecombinations, constructions and arrangements herein described andclaimed:

An object of the. invention is the provision of a ski which affordsfacilities for engagement with a surface on which the ski rests toprevent the ski from sliding backward on the supporting surface withoutinterfering with the forward movementof the ski on the supportingsurface.

A further object of the invention is the provision of a ski of thecharacter described having means for releasably holding the retrogrademovement preventing means of the device out of engagement with the supporting surface when desired.

Other objects and advantages of the invention will be apparent from thefollowing description, considered in conjunction with the accompanyingdrawings, in which Figure 1 is a side elevation of a ski embodying theinvention,

Figure 2 is a relatively enlarged plan view of the rearward end portionof the blade of the ski and of the means for pre venting retrogrademovement of the ski,

Figure 3 is a side elevation of the structnl'e exhibited in Figure 2.

In Fig. 1, I show a ski having a blade or body 1 of ordinaryconstruction equipped with the usual means, as at 2, for securing theski blade to the foot of the wearer.

It is desirable that the ski blade shall be held against any appreciablerearward sliding movement on a supporting surface, particularly when thewearer of a pair of the skis is ascending an incline or hill. To thisend, the invention provides an anti-sliding or holding plate 3 which isformed with spaced aligned sleeve portions 4 at its for ward end adaptedto be placed in alignment with sleeve portions 5 which are formed at therearward end of an attaching plate 6 which is secured by screws 7 orlike fastening devices on the rearward end portion of the blade 1 of theski. A pintle 8 extends through the aligned sleeves 4, and 5 and may beretained against accidental displacement in any suitable manner as byhaving the ends thereof upset, as shown. The antislipping plate 3 andthe attachingplate (3 thereby form leaves of a hinge and the attachingplate 6 preferably is secured on the ski blade 1 so that the sleeveportions of the attaching plates 6 will extend slightly beyond therearward end of the ski blade. Certain adjacent sleeves 4 and 5 of therespective plates 3 and 6 are spaced to provide clearance for a coiledtorsion spring 9 which encircles a portion of the pintle 8. One endportion of the torsion spring 9 extends on the upper face on theanti-slipping plate 3 and is bent laterally adjacent to its extremity asindicated at 10 to extend through a transverse eye or opening 11 in abracket 12 which is secured to the anti-slip ping plate 3 on the uppersurface of the latter by screws 13 or like fastening device, the extremeend portion of the rearwardly extending portion of thetorsion springbeing bent forward as at 1 1 to prevent accidental displacement of therearward end portion of the torsoin spring from the eye of the bracket12. The other end portion of the torsion spring extends forward on theattaching plate 6 and is bent laterally at 15 to extend through atransverse eye 16 in a bracket 17 which is secured to the attachmentplate 6 on the latter by screws vl8. The forwardly extending end portionof the torsion spring is bent rearwardly at its extremity, as at 19, toprevent displacement of the forward end portion of the torsion spring,from position on the attach ing plate 6.

The anti-slipping plate 3 is an elongated member having the side edgesof the rearward end portion thereof curved convexly to converge togetherat a point which is located in the longitudinal median line of the plate3. A relatively sharp point indicated at 20 thus is produced at thejuncture of the side edges of the plate 3 with each other at therearward end of the plate 3.

From the foregoing description of the various parts of the device, theoperation thereof may be readily understood. The torsion spring 9 willact to swing the antislipping plate 3 downwardly from the plane of theattaching plate 6 and retrograde slipping of the ski blade on asupport-ing surface will be practically prevented by reason of theengagement of the rearward end of the plate 3 with the supportingsurface. The pointed rearward end of the plate 3 will bite into thesupporting surface and will effectually prevent the ski blade fromslipping backward on the supporting surface. This is of particularbenefit when'the wearer of a pair of the skis is climbing an inclinedsurface, such as a ski slideway. When desired,

the anti-slipping plate 3 may be held out of contact with the supportingsurface and close to the upper surface of the ski blade. This is done bymeans of a pivoted retaining member or button 21 which is carried inslightly spaced relation to the ski blade on the upper face of thelatter and is adapted to be turned to and from position to overlap theadjacent end portion of the plate 3 when the latter has been swungupwardly and forwardly from the position shown in the drawings toposition to be superimposed upon the rearward end portion of theskipermit the plate 3 to swing downwardly to a relatively great angle tothe plane of the ski blade and. instant engagement of the pointedrearward end of the plate 3 with the supporting surface thus will beassured and V rearward slipping movement of the ski blade will beinstantly prevented.

Obviously, the invention is susceptible of embodiment in forms otherthan that which spring disposed on said pintle between said spacedadjacent sleeve portions, the end portions of said spring extending. inopposite directions from said pintle and the extreme end portions of thespring being turned? laterally and bent toward said pintle, meansembracing one laterally turned end portionv of the spring and securingone end of said torsion spring on theattachrng plate, means.

embracing the other laterally turned end portion of the spring andsecurlng the other end ofsaid torsion spring on said anti-slipping plateand a pivoted button carried by said ski for releasably holding saidantislipping plate superimposed upon said: ski

when said anti-slipping plate has been swung upwardly and forwardlyabout the axis of said pintle to superimposed position on said ski.
